1/4= 2/8
3/8 + 2/8 = 5/8
Therefore, 3/8 of the playground is left for the swings and play equipment
<span>Unless you have some other choices, I'd have to say Stratification, to make sure the groups are representative and heterogeneous.
I hope I helped.</span>
Answer:
JK - 20
Step-by-step explanation:
As JLM is a square triangle, so that we have the formula to calculate the corner ∡LMJ
We have tan∡LMJ = LJ/ JM =45/60 = 0.75
+) As ∡LMK = ∡KMJ => tan ∡LMK = tan ∡KMJ
+) ∡LMK + ∡KMJ = ∡LMJ
We have the formula: tan (x+y) =
=> tan (∡LMK + ∡KMJ) =
As tan (∡LMK + ∡KMJ) = tan ∡LMJ = 0.75
=> = 0.8
=> 0.75 - 0.75 x = 2tanKMJ
As 0 < ∡KMJ < => tan KMJ > 0
=> tan KMJ = 1/3
As JKM is also a square triangle
=> We have tan∡KMJ = JK/JM
=> 1/3 = JK/JM
=. JK = JM x (1/3) = 60 x (1/3) = 20
So JK = 20
An equilateral polygon has congruent sides, like a rhombus.
An equiangular polygon has congruent interior angles, like a rectangle.
In other words: Equilateral doesn't necessarily have congruent INTERIOR angles while equiangular does have/need congruent interior angles.
